To all whom it may concern:

Be it known that I, FRANK WRIGHT, a subject of the King of Great Britain, a resi dent of the town of Blairmore, Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Security Sheath Hinge and Door Fastenings, of which the following is a specification.

This invention relates to improvementsin security sheath hinge and door fastenings, and the objects of the invention-are to render the hinge and door. fastener burglar proof by preventing the removing of the same when the door is closed, to provide means whereby the hinge or fastening means proper form a cover member for screws or other like means whereby the hinge or fasteners are attached to the door, and generally to adapt the several'parts tobetter perform the functions required of them.

\Vith the above and other objects in view, the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same. J

In the drawings:

Figure l is a perspective view of one form of my improved hinge. v

Fig. 2 is a longitudinal section of the same.

Fig. 3 isa front elevation of the hinge member.

Fig. 4 is a perspective view of one of the tubular members showing the tongue on the end thereof.

Referring to the drawings: The tubular members taper toward one end and are provided at the smaller end with tongues 46.

The hinge members 47 taper toward that end remote from the hinge pin and are each prov ded with a slot 48. The tubular mem; bers 45 are secured to the door, door frame,

or to two adjacent portions of a door, by

bolts which pass through the orifices pr0-' vided in the tubular members.

the hinge members 47 into the tubular members and then bending the tongue 46 to en- "50 The door is held in position by inserting A device of the class described, comprising a tubular'tapered member designed to be secured to a door and having a tongue, a hinge member slidably engaging the tubular member and provided with a slot, means, 1

for securing the tubular member to the door, the said means under-lying the hinge member, the tongue being designed to be bent over and engage withthe 'slot, as and for the purpose specified.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
